Today, I thought I'd share a set of photos from a herbicide symptomology demonstration that I conducted in fall 2013 for our UC Weed Science School (next scheduled for fall 2015) and more recently in spring 2014 for a training session with other UC Cooperative Extension personnel.
For those of you that work regularly with herbicides of different modes of action this may be old-hat. However, many of us who get questions about herbicide injury in the field don't get always get to see comparisons under controlled conditions.
A few definitions, caveats, and brief explanations of the attached slides:

A quick post today with information about MSMA herbicides. There has been concern and lack of certainty about the registration status of MSMA and other organic arsenical herbicides. I was forwarded the attached press release and current labels for MSMA 6.6 and MSMA 6 Plus.

The red text below is copied from the attached press release.

Take care,
